Wordpress qTranslate and my website

Hello guys.

So for my new website i've installed wordpress plugin call qTranslate.
What it does is it makes instead of 1 title 2 titles one for ENG(English) and one for CRO(Croatian)-my language and one post box for ENG and one for CRO and so on so on ..
My default domain is www.mywebsite.com which domain language is ENG, but on that website you have a button on homepage to translate to CRO (my country language) and then
domain/url changes to www.mywebsite.com/cro/ and you get those "other" titles and posts on my language ..

So with all that in mind is there anything i should really watch out for SEO ? Only my default site(ENG) will be seen in Googles eyes right?

Thanks in advance.

No, all language variations should be indexed too. You may also try transposh but it is a resource hungry plugin.

Oh okay, but I want english to be the default one ..
